There really are no legal restrions, as the minimum working age is 14 in MA.
dubs, while I have no issues with young adults running a business, as long as they do it with their heart, and don't do it just to make some quick cash, and then run off (like the ones CMTHosting is referring to), there are restrictions.
I'm against children who are in it for the money, and to rip people off. I'm not against a young adult trying to make something of themselves....I've certain been there (God it seems so long ago. Now you all are making me feel old lol). In fact, we need more young adults, in today's society, taking control, and responsibility, and trying to change for the better.
